APPARATUS FOR ELEVATING AND CONVEYING COAL.

SPECIFICATION forming part of Letters Patent No. 489,886, dated January10, 1893.

Application filed May 4, 1892- Serial No. 431,858. (No model.)

To 00% whom it may concern.-

Be it known that I, STEWART WINsLow, a citizen of the United States,residing at Rutherford, county of Bergen and State of New Jersey, haveinvented certain new and useful Improvements in an Apparatus forElevating and Conveying Coal and the Like, of which the following is aspecification, reference being bad to the accompanying drawings forminga part thereof, wherein Figure 1 represents a plan view of a bargeembodying my idea; Fig. 2, a longitudinal vertical section on the line2-2 of Fig. 1; Fig. 3, an end view of Fig. 1; Fig. 4, an enlargedportion of Fig. 2; Figs. 5 and 6, means whereby the inlets to theconveyer may be closed and the ooalagitated around the mouth of saidinlet.

The object of my invention is to eliminate the element of bridging orblocking heretofore experienced in coal elevators or conveyers, and ismore particularly adapted to coalbarges,although capable of beingutilized in stationary bins or pockets.

It consists essentially of an endless belt, free from cleats or teeth ofany kind, suitably hung within a box Which is provided with inlets, andit also consists of an agitator located in the path of the descendingcoal and operated from above the coal for agitating the coal directlyabove the said inlets to prevent bridging. Doors or gates are providedfor said inlets which render the apparatus capable of discharge from anygiven portion of the cargo, thus attaining an easy trim to the barge andto a large extent easing the strains on the keelsons and eliminating toa great extent the sagging of the timbers under load,which hasheretofore been so objectionable in barge service.

To more particularly describe my invention with reference to theaccompanying drawings, a box a extends along the bottom of the barge inwhich rollers 19 are suitably pivoted and located and over which theendless belt 0 runs. The box a is provided with inlets d which areprovided with doors or gates g operated by suitable means from above theload. Directly above these inlets and operating in the path of thedescending coal are located agitators g which may consist of arms 7cprojecting from a vertical rock shaft which is operated from above theload. At the discharge end of the belt a bucket elevator of usualconstruction is located. into the buckets of which the coal isdischarged from the belt.

As to the other parts of my apparatus no'thing is new.

The operation is as follows: The coal descends to the belt through theinlets being agitated by the agitators, is carried by the belt to thebuckets of the bucket elevator, is raised to the height desired anddescends by gravity in a chute to its final destination.

One of the main advantages of my apparatus lies in the fact that softcoal can be carried as well as hard. Heretofore great difficulty hasbeen experienced in this line, as soft coal is very apt to cake and.collect itself into large masses that would effectually clog or bridgethe inlets to the conveyer and that would be strong enough to strip anycleats or teeth from the conveyor as it passed beneath. By using theagitators the coal ap 7 proaches the belt in a much finer lump and evenshould the agitator refuse to work or break, the belt will continue totravel without interruption, the lump of coal projecting through thesaid opening and forming a portion of the bridge only backing up thecoal already on the belt. Such a state of facts would, however, beeasily ascertained by watching the outputat the chute.

Having now described my invention, what I claim and desire to secure byLetters Patent In an apparatus for elevating and conveying coal and thelike in combination with a bucket elevator and a conveyer box suitably9c gated, an agitator located in the path of the descending coal as itenters the inlet, and a conveyer consisting of an endless belt free fromcleats or teeth, substantially as set
